About this network

AS53139 is operated by RDF Informatica Ltda, known commercially as RDF Telecom.

What it's used for

• The address space carries residential and business subscriber traffic, evidenced by reverse DNS entries pointing to rdfnet.com.br (e.g., 187-109-84-0.rdfnet.com.br).
• The network announces 5,120 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 26 upstream or peer neighbours. This ratio of moderate address space to a significant number of connections indicates a regional access provider rather than a transit carrier.
• As a cable and DSL ISP, the traffic consists primarily of end-user internet access, including web browsing, streaming, and VoIP services for households and local businesses in Brazil.

Notable

• Both announced prefixes (187.109.80.0/20 and 168.197.204.0/22) list RDF Informatica Ltda as the registrant, matching the AS holder.
• The inventory is composed of two distinct IPv4 blocks and a single /32 IPv6 prefix, all located in Brazil.
